United States Patent | 5,206,621 |
Yerman | April 27, 1993 |
A transformer having a barrel winding comprised of flat conductive film conductors is provided with a repeatable winding configuration by employing a dielectric metal laminate as the winding material and by patterning both primary and secondary windings on the same dielectric membrane, thereby fixing the relative positions of the primary winding and secondary winding terminals and conductors.
